Аннотация: Antarctic krill (Euphausia superba Dana) is considered a most valuable fishing object in the Antarctic waters. According to some estimates, its stocks totals hundred million tons. Besides, krill makes the basic part of feeding ration for numerous consumers, including sea birds, seals, whales, etc. Hydrochemical conditions in areas of the Antarctic krill concentrations in the Southern Ocean are reviewed. We have identified hydrochemical parameters which allow us to differentiate main water masses in the Antarctic waters (i.e. waters associated Antarctic Circumpolar Current (ACC) vs. water with the high-latitude modification associated with continental seas) and distinguish a zone of their interaction, the Secondary Frontal Zone (SFZ). This zone basically makes the areas of the krill dense concentrations.

Аннотация: Temporal and spatial variability of total productivity in Antarctic water depending on climatic conditions is considered. Favorable and unfavorable periods of commercial Antarctic krill concentration are established. The Antarctic krill is a most valuable fishing object in the Antarctic waters. It makes a basic part of feeding ration for numerous consumers. A spatial inhomogeneity of the Antarctic krill distribution is shown. Chemical indices of the high-productivity areas of the Antarctic water are established. It is shown the chemical indices of the dense Antarctic Shelf waters in the Slope areas intensified the Antarctic Slope front that is a most high-fish capacity area in Antarctic.

Аннотация: The daily dynamics of the primary producers' photosynthesis of the South-Eastern Barents Sea in the period of polar day was studied. The experimental work conducted in the Kola Bay coastal zone and on the Kola Section (33degrees30' E, 69-74degrees N). A modified oxygen method of light and dark bottles was used for the primary production estimation. Dissolved oxygen concentration was determined by Winkler. The microalgae photosynthetic activity is associated with daily PAR dynamics. All groups of marine algae retained circadian biological rhythms during polar day. The percentage of macrophytes accounted for major portion of the coastal primary production. Phytoplankton community produces about 1/3 of the total primary production. Phytoplankton starts taking the leading position as a primary organic matter producer towards the open sea. The level of primary production declines compared with the coastal area.

Main factors which impact on main characteristics of zooplaktton communities are revealed. Dynamics of abundance of Calanus finmarchicus mainly determined by intensity of warm water flux to the Barents Sea, while for rate of ice melting and predation on older individuals and females by pelagic fishes were the most important for C.lgacialis.

Аннотация: The paper presents materials on diet composition and feeding peculiarities of 16 non-target fish species in the Kara Sea in 2007-2011. Diet similarity among studied species as well as among diet of fishes in the Kara Sea and the northern Barents Sea were considered. Three trophic groups were revealed - most species (10 species) were benthivorous, 3 species - planctivorous and 3 species - piscivorous. It was shown that there are potential feeding competitors for commercial fish (polar cod, Greenland halibut). Generally the trophic structure of the Kara Sea fish community is characterized by dominance of benthivorous species (by species number) and low portion of piscivorous species, but the most abundant species belong to planctivorous fish.

Аннотация: The long-term linkages between climatic and oceanic processes in the North Atlantic, North Pacific, South Pacific (SP), and Antarctic waters for the 1950-2012 period have been studied. Based on the revealed relationships between year class strength of mass hydrobiont populations in these regions and climate variations, their state for the next few decades was assessed. In the Northeast Atlantic (NEA), the population of Norwegian spring-spawning herring (NSSH) will possibly be recruited with some strong year classes until the mid-2020s. However, the tendency toward decrease in stock biomass will continue. The biomass of Northeast Arctic cod (NEA cod) will increase, owing to appearance of strong year classes. In the Northwest Pacific, after 2017-2020 there will be two- or threeford (even four- or fivefold, under the present level of poaching) decline of the Asian salmon stocks. The main walleye pollock stocks will increase after 2017 due to appearance of stronger year classes. In the South Pacific, the oceanic horse mackerel population will remain at a low level during the next 15-20 years. The Antarctic krill stocks will grow and become more available for commercial exploitation.
